A court heard police set-up an operation to target dealers of the psychoactive substance after a number of complaints from businesses in the city.

In November last year, the undercover officer was able to buy the drug six times from the pair before they were eventually arrested.

Now, Ghani, 19, of Westgate Road, Newcastle, and Akinfolarin, 21, of St Anne’s Court, Newcastle, have been jailed for four months each after they both pleaded guilty to one count each of supplying a psychoactive substance and possessing the drug with intent to supply.
